There’s tons of nutrition information swirling around and oftentimes you’re left wondering what or who you should believe. Here are 7 signs that you’re receiving bad (and sometimes even dangerous) nutrition advice.

#1: Lack of Significant Research
Nutrition advice should be based on significant scientific research that was conducted in peer-reviewed journals over months or even better, years. The majority of the research will back up a specific theory with a few straggler studies that may point at the other side. If you’re being quoted a study, be sure what you are being told reflects all the research in that area. In addition, ask who sponsored the research as sponsored studies may be one sided. Oftentimes, this will raise a big red flag if someone hasn’t done their homework.

#2: Lots of Persuasive Anecdotes
You may find a diet or a diet expert with tons of followers who all swear that the diet plan or advice is THE BEST they ever followed. These folks will tell you how they lost hundreds of pounds—and that you will too.

Although it may sound like you MUST try it, it’s important to remember that every person is different and has individualized needs. Some diets or advice may be not be safe for folks on certain medications or with certain diseases (like Parkinson’s or diabetes), so you need to check with your doctor before trying anything new. It’s also important to make sure the science is also there to back the advice up — just relying on anecdotes just isn’t enough.
